Integrate GridFunction over certain elements

Hi! I’m trying to check some properties of a method I implemented and to do so I need to get \int_el u dx for every element and check its sign, but I couldnt find any way to perform that integral with grid functions.

Integrate (u, mesh, element_wise=True)

returns a vector of element-wise integrals

Ooh, I see, I saw that flag but didn’t get that it returned a vector, thanks @joachim !! Also, are there plans to generate a “Numpy like” documentation? In the sense of a page for every function or class and its args, kwargs, flags and returns? If so I would like to help any way I can!

well, you can do

import ngsolve
dir (ngsolve)

and then

help (ngsolve.Integrate)

Guess we could generate html pages from the docstrings, which would simplify googling.

Sounds good, thanks for your comments :slight_smile:
